The 5 pairs of abdominal plates, which meet in the median line on the dorsal side, extend around 
the sides of the abdomen and gradually almost come together on the ventral side", the last pair being 
very much closer together than the first pair. The last two pairs of plates are almost concealed by 
the overlapping plates of the preceding segments. 
The extremity of the abdomen is truncate and without uropoda. The pleopoda (fig. 7 c) are 5 
pairs of double-branched tapering appendages, all simi- 
lar in shape. 
There are 5 pairs of incubatory lamell*, which form 
the ventral side of the marsupial pouchy enclosing it 
completely, the lamellse overlapping in the median line. 
Seven pairs of small, feeble legs are present, a pair 
or each segment of the thorax. 
The male (fig. 8) is narrow and elongate and with- 
out any color markings. The head is very large and 
without eyes. The 7 segments of the thorax are about 
equal in length, each one carrying a pair of appendages, 
so that there are 7 pairs of thoracic legs in all. The 6 
segments of the abdomen are distinct, the terminal one 
being rounded and carrying a pair of single-branched 
appendages, the uropoda; the 5 preceding abdominal 
segments are provided each with a pair of single- 
branched, well-developed pleopoda. 
A large number of specimens were obtained by the 
U. S. Fish Commission: steamer Albatross on the north 
and northeast coast of Main Island, Hawaiian Islands, 
and the northeast approach to Pailolo Channel, between 
Main Island and Molokai Island.
